12 Post processing method of measuring shot noise

(1) If a post processing method is used, the stored LZpeak level measurements may be reviewed with one or more of the following to obtain the level of each shot—

(a) suitable identifying markers for each audible shot attached to the data,

(b) time-synchronised audio,

(c) time-synchronised data from the range.

(2) If the measurements are reviewed using a post processing method that complies with this section—

(a) if the difference between the level of a shot and the preceding LZpeak level is 5dB or greater—the noise level of the shot must be classified as Category A, or

(b) if the difference is greater than 0dB but less than 5dB—the noise level of the shot must be classified as Category B, or

(c) if the difference is 0dB but the shot is audible—the noise level of the shot must be classified as Category C, or

(d) if the shot is not audible and not measurable—the noise level of the shot must be classified as Category D.

(3) If time-synchronised data from the range is used, an observation must also be made at a location that has an unobstructed view of the firing line.
